GILLETTE SAFETY RAZOR COMPANY, OF BOSTON, MASSACHUSETTS, A CORPORATIONor DELAWARE application mea July 2o,

One of the objects of my invention is to provide a safety razor having apivotally supported blade holder and a pivotally supported guard memberso arranged that the blade holder with a blade and the guard may befolded within the frame and may be extended into shaving relation withmeans to retain the guard and .blade holder in either of said positions.In a specific embodiment in of my invention illustrated intheacompanying drawings I provide spring-acting means cooperative with therazor frame' and the guard member for retaining the latter and the bladeholder in shaving relation and for i5 retaining said parts in foldedrelation within the frame.

M invention is applicable for use in connectlon with a safety razor inwhich means are provided for rotating or rocking the blade holder withthe blade for stropping the edge of the latter. Ihave illustrated myinvention as embodied in a safety razor in which a roller is carried bythe mainframe and is geared to the blade holder for rotating or rockingthe latter, a portion of said roller projecting'beyond the frame inposition to engage a surface for causing rotation of the roller torotate or rock the blade holder for presenting opposite edges of theblade to `a sharpening surface. The last named class of vrazor is setforth in my application for Letters Patent filed April 14, 1927, SerialNo. 183,686.

I provide means for locking the gearing I when the guard member and theblade holder are folded within the frame to keep said parts in foldedrelation ine a compact manner for l storage and transportation.

My invention comprises novel details of improvement that will be morefully hereinafter set forth and then pointed out in the claims. i

Reference is to be had to the accompanying drawings forming aparthereof, wherein Fig. l is a partly sectional side view of SAFETY nazca1927. Serial No. 207,036.

Similar numerals of reference indicate corresponding parts in theseveral views.

The frame 1 of the razor illustrated includes a base 1a and spaceduprights 1b to which a handle 2 is attached. A blade holder 3 ispivotally carried by and between the uprights 1b and shown provided withpivots 3a that are secured to ears 3b extending laterally from the bladeholder. The pivots may be secured to the blade holder by means ofsquared ends riveted tothe ears, as indicated in Fig. 4. A blade 4 isdetachably carried by the blade holder, and the blade holder and bladeare of such a length as to swing freelyv between the uprights 1b andwithout engaging the base 1a. The guard 5 for the blade is pivotallysupported between the uprights 1b, being shown carried by pivots 6 thatare supported by the uprights 1b so that the guard may swing between theuprights, (Fig. 5). A roller 7 carries a gear 8 that 1s in mesh with agear 9 that is firmly connected to the blade holder, being shownattached tothe corresponding pivot 3a, wherebywhen the roller 7 engagesa surface 10 and is reciprocated along the same the roller will v.berotated to causel rotation or rocking Vof the bladel hold er by means ofthe gearing. The roller l0 rojects beyond the adjacent portion .of

ame 1 vin order to engage the surface 10.

While Ivhave shown a roller 7 and ears 8, 9 atvopposite sides of frame 1it will e understood that one roller with the corresponding gears 8 and9 may be used if preferred.

The guard is shown pivotally carried on the pivots l6 and when the guardis extended 4outwardly the blade may be rested thereon for-shaving, asin Fig. 1. The blade holder and the guard may be folded within the frame1 between the uprights 1b in a compact way for storage andtransportation, as indicated in Fig. 4. The guard is shown providdedwith stop means 5a adapted to engage the blade holder when the ard is inshaving position, the guard havlng hooks 5b to engage and retain theblade, as shown in Fig. 1.

' At- 11 are links pivotally connected with the guard member at 12. Thelower ends of' the links extend through openings 1c in base 1a and areconnected to a spring 13 that is shown secured to the base. The handle 2is shown provided with a reduced end portion 2a that passes through ahole in the spring and in the base and is riveted over izo-secure saidparts firmly together. For convenience the free ends of the spring 13are shown bent laterally and extending outwardly at 13a and are `locatedin the openings 1c of the base to freely enter openings 11a at theadjacent ends of the links 11, whereby the tendency xof ,the springswill be to push the links upwardly (in the drawings) to maintain acorresponding tension on the guard. The position of the pivots 12 withrespect to the pivots 6 of the guard member is such that whenl the guardis moved outwardly from the frame and the blade is rested against .theguard the spring 13 will push the links and thereby will push the guardtoward the blade so that the stop means 5a of the guard will engage theblade holder 3 and retain the guard and the blade in shaving relation,as illustrated in Fig. 1, the pivots 12 being at one side ofthe axis ofthe guard. The blade and blade holder may be pushed downwardlyr andinwardly to the positions shown in igs. 2 and 3, whereupon the spring 13will permit the links to move. When the parts are in the position ofFigs. 3 and 4 the outward tendency of the spring will be to push thelinks and thereby, because the pivots 12 are then at one side of'a planethrough the spring and pivots 6, (on the side of the axis of the guardopposite that shown in Fig. 1), will cause the guard to be retainedfolded within the frame, since the end portions of the guard will bearagainst the links.

Means are provided to retain the blade holder and the blade in closerelationto the guard member and folded therewith within the frame, asillustrated in Figs. 3 and 4, I have illustrated an adjustable lockingmember 14 slidably carried by one ofthe uprights 1b and having a reducedend por-` tion or projectionv14a adapted to engage the adjacent teeth ofgear 8, as illustrated m Fig. Locking member 14 is shown .provided witha projection or pin 15 headed at opposite. endsY and slidable in a slot`1d in the adjacent upright 1b, the outer surface of the upright 1bVbeing shown outwardly pressed forming a projecting portion at 1e in thenature of a guide, andthe member 14 being shown recessed or channeled at146, whereby the member 14 is slidably guided to engage and disengagethe adjacent gear 8, (Figs. 6 and 7), and is -kept from rotationrelativel to the gear. When the guard and the bla e holder are to befolded within frame 1 the locking member 14 is to be disen aged fromgear 8, and when the guard antgl the blade holder are in the positionshown in Fig. 3 the locking member 14 will be pushed into engagementwith gear 8 to retain the parts folded. When the blade is to be used forshaving the locking member will be released from gear 8 and the guardwill be pushed laterally from the frame, so that the spring 13 willoperate through the'links 11 to present the guard outwardly lincooperation with the blade holder, as in FiJ 1.

he blade holder may be of any desired construction. In the exampleillustrated the blade holder includes a plate-like member 3c againstwhich the blade is laid, said member being shown l'provided withprojections or pins 16 adapted to pass through holes 4a in the blade toretain the blade in pro er position on the plate 3c, (Fig. 8). A laderetaining member 3d is curved to have a normal outward spring tendency,as indicated in Fig. 9a, and said member is shown at one end slldablyguided in an aperture 3e Y in a din lug 3f struck u from the plate 'll gP i 9b, and the blade will be laid upon the holder member 3c, whereuponthe member 3d will be llaid against the blade. as illustrated in Fig.9a, and will be pressed against the same fiatwise under spring tensionand will .be

slid along the blade to enter the projecting portion 3,.into the o ning3j to lock the parts to ther, as in 'gl 9. To remove the blade itlsmerely necessary to slide the member 3d reversely to that ldescribedso that the'blade may be removed from between the i i members 3c and 3d.u

When the blade is to be sharpened the guard will be folded within theframe and will be retained by the links 11 and spring 13, as'in Fig. 4,and the blade holder and 4the blade ma be swung outwardly from theframe.' T e razor may then be applied to thev stropping surface 10, asindicated in Fig. 10, and by reciprocating the razor alon said surfacethe contact of the rollers g therewith will, through the gearing, causerotation or rocking of the blade holder to present opposite sides of theblade edge alternately to'the surface, the blade swinging through theframe as required from side to side. Byreciprocating the razor alongsurface the blade edge will be draggedvupon said surface for sharpeningsaid edge. A
